WOW Input QueueWin3.1 and earlier had only one input queue for all user interface requests. Win16 recreates this environment, so each VDM and WOW pair has one input queue for all Win16 applications in that particular VDM/WOW pair. Running applications can interfere with each other.

Scheduling in WOW
Win3.1 and earlier distributed execution time with cooperative multitasking. Win16 within a VDM/WOW multitasks cooperatively. In NT, the applications run cooperatively within the VDM/WOW pair but multitaskpreemptively between the VDM and the rest of the 32-bit applications.

Additionally, lj says: You might want to mention the 'run in a separate memory space' checkbox, which causes NTs to start a new wow for the process. It seems to have disappeared in XP, though.

WOW is also a music compilation series put out by Word Entertainment. I believe it stands for "World of Worship". Basically, a new compilation comes out every year or so, and contains two CD's featuring some music exec's choices of the best songs from the past year. What this means, basically, is 20 "adult contemporary" songs, 5 soft pop teenybopper songs, a Veggietales song, and few nods to the rest of the industry.

Recently, though, Word has been slightly more considerate, and has arranged songs between the two CD's with respect to differing listener preferences. Each of the more recent compilations has a Silver Disc, containing what older listeners may prefer, and a Colored Disc, containing the rest of the songs.
